그리고 `/openapi.json`, `/docs` 또는 `/redoc`의 URL로 이동하면 `404 Not Found`라는 오류가 다음과 같이 표시됩니다:

```JSON

    "detail": "Not Found"
}

     *

$ OPENAPI_URL= uvicorn main:app

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

Então, se você acessar as URLs em `/openapi.json`, `/docs` ou `/redoc`, você receberá apenas um erro `404 Not Found` como:

```JSON
{
    "detail": "Not Found"
}

$ OPENAPI_URL= uvicorn main:app

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

Then if you go to the URLs at `/openapi.json`, `/docs`, or `/redoc` you will just get a `404 Not Found` error like:

```JSON
{
    "detail": "Not Found"
}

```console
$ OPENAPI_URL= uvicorn main:app

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

之後若你造訪 `/openapi.json`、`/docs` 或 `/redoc`，會看到如下的 `404 Not Found` 錯誤：

```JSON
{
    "detail": "Not Found"
}

				const ticksPerSecond = 1e7    // Windows timestamp resolution
				ts := int64(attrBuf.uint64()) // ModTime since Windows epoch
				secs := ts / ticksPerSecond
				nsecs := (1e9 / ticksPerSecond) * (ts % ticksPerSecond)
				epoch := time.Date(1601, time.January, 1, 0, 0, 0, 0, time.UTC)
				modified = time.Unix(epoch.Unix()+secs, nsecs)
			}
		case unixExtraID, infoZipUnixExtraID:
			if len(fieldBuf) < 8 {
				continue parseExtras

また、生成されたスキーマが [OpenAPI](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md) 標準に従っているので、互換性のあるツールが多数あります。

このため、**FastAPI**自体が代替のAPIドキュメントを提供します（ReDocを使用）。これは、 [http://127.0.0.1:8000/redoc](http://127.0.0.1:8000/redoc) にアクセスすると確認できます。

同様に、互換性のあるツールが多数あります。多くの言語用のコード生成ツールを含みます。
